Application filed Jui es, i913. Serial No. 775,278.

To allwho'm, it may concern:

Be 1t known that.I, 'ALFBED A. Znzennn,

a'citizen'of' the United States, residing at Boston, in the county of Sutlolk'a-nd State of Massachusetts, have invented an Improvement 1n Bonding Devices for Balls, of

which the following is a specificatiom the loops are concealed for a substantial portion of their length and hence do not admit of immediate inspection, or they are connected with the tie-plate or with the attaching-means for the tie-plate in such manner as to interfere therewith and cause trouble, particularly between the men who have charge of the track, and the men who have charge of the signal-system, and, so

far as I am aware no support wire loop has ever been adopted. I

This invention has for its object the constructionof an improved form of support fdr a bond-wire loop which is adapted to be arranged on the attaching-bolt of the tieout its length.

plate and to be held by said bolt regardless of Whether said bolt is tight or loose, said support being constructed and arranged so as to receive the bond-wire in such manner as to hold it, and also to admit of its removal and of its ,replacement without inter-' with-the attaching-bolt, and also to fering throughadmit of its immediate inspection Figure 1 is a front elevation of a bonding-device for rails having supports forthe bond-wire loops embodymg this invention.

any usual or suitable construction. The

bond-wire support embodying this invention consists essentially of an annular plate 25, adapted to be arrangedv on the shank. of the attaching-bolt and beneath the head of said bolt, thereby to occupy a position between the head of the bolt and the tie-plate. Said annular plate has an elongated or ovalshaped hole through it, which corresponds in shape and size with the usual elongated or oval-shaped hole in the tie-plate, and it I is usually made flat to bear against the flat faceoi' the tie-plate, and as here shown, it has ears 30, extended from it, respectively, at the top and bottom, the end-portions of which are bent to form hooks to receive the bond-wire loops. The'uppermost ear is bent forward and then its end-portion is bent'upward and rearward, thereby to form arecess of the bond-wire loop and to provide a space between the end ofthe ear and the tieplate for the introduction of said loop and also to form a seat'on which the loop rests when placedtherein, as represented by full lines Fig.3. After the bond-wire loop has been placed in the recess the end-portion of the -ear may be further bent rearward until it engages or nearly engages the face of the tie-plate, as represented by dotted lines Fig. 3, thereby'closing the entrance to the recess formed therein. The lowermost 'ear is bent forward and upward to form a hook to loosely receive and support the bond-wire loop, as represented by full lines Fig. 3, and

'afterthe bond-Wire loop has been placed in the recess of the hookthe end-portion of the ear or hook is bent rearward, as represented by dotted lines Fig. 3, until it engages or nearlyengages the face, of the -tie-plat'e.

The metal composing the annular plate is sufficiently ductile to enable its earsto be bent in this manner. Each bent ear is designed to receive a single bond-wire loop, and, as it will be observed, holds the'same yet permits removal whenever desired, and in case of removalit permits of the intro- -duction of a new wire by passing the end thereof through the recess. The support ad.-" mits of the bond-wire being inspected 105 quickly throughout its length.
